Description

[Detailed explanation of the idea] "Purpose of invention" a Industrial application field The present invention relates to copper roofing sheets for flat roofing.

b. Prior art: The four circumferences of the roof board are folded to an appropriate folding width, a folding line is formed, and a notch is provided which vertically divides the rectangular part formed by the lower folding line and the folding lines on both sides into two. , one side of the engagement edge is folded back to the bottom surface, the other side of the engagement edge is folded back to the top surface, and then the upper engagement edge is folded back to the top surface,
There is a roofing board in which the lower engaging edge is folded back to the lower surface. (Utility Model Publication No. 50-45249) c Problems to be solved by the invention In the conventionally known invention, when the lower engaging edge is folded back to the lower surface in the final manufacturing process, the corner of the engaging edge forming the notch is Corners are crushed. That is, by providing a notch in the lower corner of the engaging edge, the engaging edge can be engaged and joined from side to side without colliding with each other, but when a roof with a gentle slope is formed, the joining part Since there are no overlapping parts, there is a risk of rain leaking. Further, the folded portion between the upper engagement edge and the engagement edge is also crushed and cannot be joined to the left and right sides. Therefore, in order to join the left and right sides, it is necessary to provide a gap in the folded portion, and if the upper engaging edge is bent upward with the gap provided, the upper corners of the engaging edge will protrude slightly. , the protruding portion will get in the way and prevent complete bonding.

``Structure of the invention'' a Means to solve the problem Fold the rectangular copper plate parallel to the left side, the right side, the top side, and the bottom side. In addition to providing each curved line, each corner that is continuous with the rectangular part surrounded by the vertical folding line and the horizontal folding line outside the vertical folding line is shaped like a dogleg so that a chevron-shaped convex part is formed. Cut it out, and fold it back with the left folding line facing upward, the right folding line facing downward, then the upper folding line facing upward, and the lower folding line facing downward, keeping a gap between each folded part. The present invention provides a cassette-type copper roofing plate that is easy to join horizontally and vertically and can reliably form a roof that does not leak from the joints.

b. Effects and Examples Therefore, according to the present invention, a desired number of copper roof panels are joined on the left and right by fitting the vertical lower seams and vertical upper seams adjacent to each other on the left and right, and then the joined The copper roofing sheets are laid flat by sequentially engaging the lower side seams of the copper roofing sheets.

An embodiment of the present invention will be explained below with reference to the drawings. As shown in Fig. 1, a folding line 1 is parallel to the left side of a rectangular copper plate, a folding line 2 is parallel to the right side, and a folding line 2 is parallel to the top side of a rectangular copper plate. Fold line 3 parallel to the bottom side and fold line 4
are provided respectively, and both corners that are continuous with the rectangular portion surrounded by the folding line 1 and the folding lines 3 and 4 outside the folding line 1 are cut out in a dogleg shape so that the chevron-shaped convex part 5 is formed. Then, it is cut out in a dogleg shape so that a chevron-shaped convex part 5 is formed at both corners that is continuous with the folding line 2 and the rectangular part surrounded by the folding lines 3 and 4 outside the folding line 2, and then As shown in Figures 2 to 5, fold the folding line 1 upward and keep a small gap 6 between it and the top surface of the rectangular copper plate to form a vertical upper seam 7, and fold the folding line 2 downward to form a rectangular shape. Hold a small space 6 between the bottom surface of the copper plate and fold it back vertically and lower it 8.
, and fold the folding line 3 upward to allow a small space between the top surface of the rectangular copper plate and the top surface of the vertical top 7.
6 is held to form a horizontal upper seam 9, and the folded line 4 is folded downward, and a small space 6 is held between the lower surface of the rectangular copper plate and the lower surface of the vertical lower seam 8, and a horizontal lower seam 10 is formed.
By forming the copper roof panels 11 with gaps 6 in the folded portions of each panel, the vertical upper panels 7 and the vertical lower panels of a large number of copper roof panels 11 are formed as shown in FIG. 8 and 6 to join the bottom row of copper roof panels 11 from side to side. Next, position the center of the lower horizontal seam 10 of the second row of copper roof panels 11 at the position where the upper vertical seam 7 and the lower vertical seam 8 are engaged, and engage the lower horizontal upper seam 9, 9. Then, the copper roof sheets 11 are sequentially joined upwards and the roof is laid flat. In FIG. 6, 12 is a hanger.

``Effects of the invention'' Because this invention is constructed in this way, the work efficiency is significantly improved compared to the conventional construction method in which vertical and horizontal seams are grabbed and flat-roofed on site. The difficulty of grasping the horizontal top seam of the board is eliminated, and the finish is beautiful.Furthermore, the joints of each corner of the copper roofing board 11 are connected between the vertical top seam 7 and the vertical bottom seam 8. 6 is fully inserted and overlapped over almost the entire surface, the lower corner of the joined vertical seam is bag-shaped, and the rain closure is perfect, and there is no risk of rain leaking from that location due to capillary action.

Since a chevron-shaped convex portion 5 is provided at each corner of the rectangular copper plate by cutting and the vertical and horizontal seams are folded back, the upper and lower portions of the vertical seams have protrusions as in the conventionally known device. Since there are no screws, it is easy to engage. Also, the roofing work is done by each copper roofing board 11
By engaging the vertical and horizontal seams and attaching the hangers 12 to the roofing boards, construction can be easily and quickly done without requiring a high degree of skill, and work efficiency is significantly improved. It has excellent wind resistance due to its fixation and deep engagement of each gob.

As described above, the present invention is a useful device that has a simple and solid structure and can be mass-produced at low cost.
